CIA: We're 'reviewing our performance'

A Central Intelligence Agency spokesman says that the agency is conducting a review of the situation that led to the resignation of former director David Petraeus.

"At the CIA we are constantly reviewing our performance. If there are lessons to be learned from this case we'll use them to improve. But we're not getting ahead of ourselves; an investigation is exploratory and doesn’t presuppose any particular outcome," agency spokesman Preston Golson said in an emailed statement.

Petraeus resigned last week after an FBI investigation revealed that he had an affair with his biographer Paula Broadwell, who allegedly sent threatening emails to a Tampa woman she perceived as a romantic rival.

The scandal has since widened to include a separate Department of Defense investigation into the conduct of Gen. John Allen, the Obama administration's nominee to be Supreme Allied Commander Europe, who also allegedly communicated with the woman in Tampa.

The probe is to be conducted by CIA's inspector general. The news was first reported by the Associated Press.
